Translation of tiefgründig

I wanted to tell you that we have uploaded a successful version (with Peter). In Annex I send the profile. It is very similar to the last version, just a few words less in each lesson.
The fact that I have received many emails from students in order to make Vocabulix known is a personal success for me. But I think that a new website with many pages would be better for future uses.
Thank you for your email, everything was crystal clear. We should call each other, this would be the best way. Do you have the same opinion? But I think I need more help, for example: how do you conjugate swim?
